This invention relates to cement molding The ears are so arranged thatthey interlap, apparatus, one within the other, as indicated in FigureObjects of this invention are to provide a 2, and this scheme isfollowed throughout cement molding apparatus which may be the entiredevice.

These extensionplates cia-ins tight and holding the core portion are similarly providedwith pairs of ears 7. rigidly locked and braced.

' Asshown in Figure 1, it may be desirable to provide cut away portionstorthe corners of the cores. This is readily secured by shaping thecorner members 9 as shown in Figure 1. Obviously, othenshapescould beemployed.

If it desired to provide apostwith cut 3 away corners, it is merelynecessary to em- I ploy the construction shown in Figures l andproximatelysquare sections, it is clear that they may be adjusted forother rectangular ..sections by the proper selection of spacing plates.

It is also clear that any number or these spacing'plates may be used, orthat the spacing plates maybe of different sizes although it. ispreferable tohave a large number of spacing plates'so that the devicemay be built up as desired. I

It will be seen that a 'verysimple and serviceable type of'moldingdevice for -ce- 'ment' has been provided which may be rapid- ;ly'used toform posts either hollow or solid. Fiirther,'it is to be noted that theside bars 4 form efiicient handles for lifting the mold out of place.Furthen'the core may be readily removed by grasping the chains 16 andsliding the core-upwardly.

"It is=to be'n'oted also that the device is rugged and cannot be readilydamaged. When it is appreciated that these devices are subjected togreat abuse'in the ordinary service in whichthey are used, it isclearthat this -feature is highly desirable.

"Further, it will be seen that 'the'xdevice may be very cheaplymanufactured as it is relatively simple, and that it "is composed offarelatively small number of parts.

Althou'gh the invent-i on has been described in considerabledetail, suchdescription'is intended as illustrative rather than limiting astheinventi'on maybe variously embodied and as the scope of suchinvention is to be determined as claimed.

7 I claim:

1. A cement molding apparatus comprisingan outer. body member and aninner core member, said outer body member and said inner-core membereach having corner portions, and: intermediate plates betweensaid cornerportions, said plates and'said corner portions each having a series ofears for holding such portionsin relative position, and means forlocking the corner portions against outward separation.

111* a cement molding apparatus, the combination of a plurality ofcorner membershai'ing"guides thereon, bars passing through said guidesand extending from one cornermember to the next corner member,

intermediate plates located between said corner n'ien'ibers, and meansfor locking said guides to said bars. 1

3. In a cement molding apparatus, the

combination of corner members, U-fsh'a'ped combination or cornermembersfU-shaped guides rigidly carried ,by'said corner members andprojecting outwardly therefrom, liars passing through said U-shapedguides, said guides having aperturesItherethrough, tapered pins passingthrough said apertures for locking said guides tosaidbars','intermediate plates positioned between said corner members, andtongues carried bysaid plates and said corner membersfor holding saidplates in posit-ion. p j

5. In a cement m'olding apparatus, the combination of corner members,chains extcndingdiagonally from one corner member to the other,intermediate plates located between said corner members, and means fortensioning said chains, while said-intermediate members remainstationary.

6. In a cement molding 1apparatus, the combination of :tour cornermem'bers,'twoof said corner members having spaced plates providedwithjapertures withthe diagonally opposed corner members having platesprovided. with hooks, chains carried]by"said hooks and extendingdiagonally towards the corresponding pair of spaced plates, a slottedplate carried by the free end of each of said chains and located betweensaid spaced plates, wedges passing through said spaced plates andsaidslotted plates for tensioning said chains, said corner members beingspaced apart, removable intermediate plates located between saidcornermembers; and means for -holding said intermediate plates againstlateral displacement. v I

In testimony that I claim the foregoing I have hereunto set my hand atMilan,"Italy.
